摘要:
通过对塔里木盆地柯坪露头志留系依木干他乌组中遗迹化石的研究,鉴别出6 属7 种。化石分子有Chondrites isp.,Gordia.isp., Helminthopsis aff. abeli, Ophiomorpha nodosa, Planolites beverleyensis, Planolites montanus, Thalassinoides isp.。这些遗迹化石具有较高的分异度和较低的丰度。按古生态或造迹生物的行为习性分类,可分为3 种生态类型:①居住迹(Domichnia),Ophiomorpha nodosa, Thalassinoides isp.;② 进食迹(Fodinichnia),Planolites beverleyensis, Planolites montanus, Chondritesisp.;③觅食迹(Repichnia),Gordia isp.,Helminthopsis aff. abeli。根据遗迹化石的古生态特征、沉积序列上的分布特点及围岩和沉积构造特征,依木干他乌组的遗迹化石可归为Planolites -Chondrites 遗迹组合,属于Cruziana 遗迹相,形成于泥坪沉积环境。
Abstract:Based on the analysis of trace fossils collected from the typical outcrop of the Silurian Yimugantaw Formation in the Kalpin area, the authors identified seven ichnospecies of six ichnogenus in Yimugantawu Formation. The ichnospecies mainly consist of such common trace fossils, i.e., Chondrites isp., Gordia.isp., Helminthopsis aff. abeli, Ophiomorpha nodosa, Planolites beverleyensis, Planolites montanus and Thalassinoides isp.. The trace fossils are of high diversity and low abundance. According to their palaeoecological, behavioral and ethological features, these trace fossils belong to three ethological categories: ①Domichnia:Ophiomorpha nodosa, Thalassinoides isp.;②Fodinichnia:Planolites beverleyensis, Planolites montanus, Chondrites isp.;③Repichnia:Gordia isp., Helminthopsis aff. abeli. These trace fossils can be assigned to Planolites-Chondrites ichnoassemblags and can be diagnosed as the Cruziana ichnofacies. According to the composition and distribution characteristics of these fossils in the sedimentary sequences and the characteristics of country rocks, these trace fossils might have formed in a mudflat sedimentary environment.
